The proportion of divorces initiated by women climbed to more than 70%

Tragically, however, government policies intended to deal with the “fatherhood crisis” have been ineffective at best because the root cause is not child abandonment by fathers, but policies that give mothers an incentive to initiate marital separation and divorce.
Women file about 70 percent of divorces, and about 80 percent of divorces are unilateral, according to Howard University political scientist Stephen Baskerville.

Other studies have reached similar conclusions. The proportion of divorces initiated by women climbed to more than 70 percent when no-fault divorce was introduced, according to Margaret Brinig of the University of Iowa and Douglas Allen of Simon Fraser University. Mothers “are more likely to instigate separation, despite a deep attachment to their children and the evidence that many divorces harm children.” And the “bottom line” is indeed the children. After analyzing 21 different variables, Brinig and Allen concluded that “who gets the children is by far the most important component in deciding who files for divorce.” Author Robert Seidenberg goes further, reporting that “all the domestic relations lawyers I spoke with concurred that in disputes involving child custody, women initiate divorce almost all the time.”

In the largest federally funded study ever undertaken on the subject, Arizona State University psychologist Sanford Braver demonstrated that few married fathers voluntarily leave their children. Braver found that overwhelmingly it is mothers, not fathers, who are walking away from marriages. Moreover, most of these women do so not with legal grounds such as abuse or adultery but for reasons such as “not feeling loved or appreciated.

The most serious effect of forcibly removing fathers after quasi-criminal accusations is the abuse of children it induces. Contrary to popular belief, it is not fathers, but mothers—especially single mothers—who are most likely to abuse children. An HHS study found that women ages twenty to forty-nine are almost twice as likely as men to be perpetrators of child maltreatment: “It is estimated that . . . almost twothirds [of child abusers] were females” (HHS 1998a, xi–xii)

Statistics tell us that women instigate more than 75% of today's divorces. This flight of women from marriage has prompted books such as Maggie Gallagher's The Abolition of Marriage: How We Destroy Lasting Love. Gallagher calls for a return to fault divorces as a "cure" for divorce. She feels the individual's right to choice and self-gratification has brought an "institution" to the brink of extinction.
